In a method or a transfer station for a digital printer, liquid developer with toner particles can be directed towards a first side of a recording medium and onto the first side of the recording medium at a transfer point. A transfer roller can be configured to direct the liquid developer towards the recording medium. The toner particles can have a first polarity and the recording medium can move past the transfer roller along a transport direction. A layer of charged particles can be applied from a second side of the recording medium by a surface charging station. The surface charging station can be arranged before the transfer point in the transport direction. The second side of the recording medium can be opposite the first side. The charged particles can have a second polarity that is opposite the first polarity.
